Drilling teeth is an essential part of repairing and restoring the damage caused by tooth decay. For generations dentists have relied on the dental drill with its rotating burr to remove decayed and damaged tooth material.

But while the dental drill is effective it also has its disadvantages. In the process of removing decayed material it inadvertently removes healthy structure near the target material. It often requires anesthesia to deaden the work area. And its noise and vibration are often unsettling to patients.

There is a growing alternative, though: air abrasion, a technology that's been around since the mid-20th Century. But recent advances in controlling the dust created by using abrasion, as well as new tooth-colored bonding materials to replace tooth structure, have sparked new interest among dentists and patients alike.

Also known as particle abrasion, this drill alternative uses a pressurized stream of fine particles to remove decayed material. Using a hand wand a dentist can precisely aim the stream of particles (usually aluminum oxide) to the specific areas of decay or softened material that need to be removed. As a result, it removes only a fraction of healthy tooth structure compared to traditional drilling. Air abrasion has also proven effective for removing staining without harming enamel.

Air abrasion also eliminates the sound and vibration associated with dental drills, and may not always require local anesthesia. On the other hand, it does have some limitations. For one, it's not as effective with larger cavities or working around older fillings. The tooth or teeth to be worked on must be carefully isolated from the rest of the mouth to keep the patient from swallowing the abrasive particles. And without a high-volume suction pump and good isolation protocols, the particles can produce something of a “sandstorm” in the treatment room.

But as air abrasion continues to advance, we may see improvements in these limitations. In a future time, the traditional dental drill may go the way of the horse and buggy.

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.

In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.

Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.

What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.

Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.

A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment. You can read more about bruxism in the Dear Doctor magazine article “Stress and Tooth Habits.”

The big day you've waited for all your life is just around the corner — your wedding day! And to make that day as special as possible you've been working on making yourself more attractive.

In all your preparations, don't forget your smile. There are many ways to make it shine, some requiring little time or effort. A professional dental cleaning and polishing, for example, can do wonders for brightening your smile. If you have above normal staining, you can also undergo professional whitening to remove stains and enhance your teeth's natural color.

Some problems, though, like chipped, slightly misaligned or heavily stained teeth may require more than a cleaning or whitening session. In these cases, you might consider covering these less attractive teeth with porcelain veneers to transform their appearance. As the name implies, veneers are a thin layer of tooth-colored, translucent porcelain custom designed for you and bonded permanently to the visible tooth.

While veneers can significantly change your smile, it can't fix every appearance problem. Some teeth require more extensive dental work, like a porcelain crown that completely covers a tooth, or dental implants to replace missing teeth. In more complex situations you may want to look at orthodontics to repair an unattractive bite, or plastic surgery to change the look of a gummy smile.

Keep in mind, though, many of such treatments take time: installing dental implants can take months and some orthodontic treatments, years. As soon as you can, you should discuss your smile appearance with your dentist and what can be done to enhance it in the time you have.

With the help of your dentist, orthodontist or other specialist, you can change your smile. And that, along with all your other preparations, will help make that once in a lifetime day even more special.
